Heaviside Cover-up Method for partial fractions (1 Viewer)

[leehuan]

Pretty amazing tool, and I know how it works.

Can someone explain why it works? Is there a proof for this method's validity?

Can you refresh our memories of what it is ? Probs know it but not the name

It obviously works because let me give an example :

If you equate the tops of both equations

The process of the Heaviside Cover-up method works because the substitution replicates the results of Drsoccerball's generic substitution method.

Heaviside allows you to skip the step of common denominating

I didn't know "denominate" was a word.
I would have thought that would have a different meaning:
"I nominated him for captain, but he pissed me off so I denominated him".

Ah, of course. Simple things missed. Thanks
